PROBLEM TO BE SOLVED: To provide a seedling transplanter provided with a turning rotor for ground working which can level a field without leveling too much even upon turning.SOLUTION: The seedling transplanter includes: right and left ground-leveling rotors 27a and 27b for leveling the field surface, provided for a lower part of a seedling planting part 4 for planting seedlings to the field, the seedling planting part provided for a rear part of a traveling vehicle body 2 and right and left rear wheel gear cases 18 for supplying a driving force of an engine 20 to rear wheels 11. The seedling transplanter also includes right and left separate rotor drive shafts 70a and 70b for each independently supplying the driving force from the right and left gear cases 18 to the ground-leveling rotor 27a and 27b on both right and left sides, and is configured so that the ground-leveling rotor driving shafts 70a and 70b on a rotation inside rotate at lower speed than the ground-leveling rotor driving shafts 70a and 70b on a rotation outside upon rotation operation, thereby preventing mud in the field from being too soft and flowing with the ground-leveling rotors 27a and 27b in the rotation inside.COPYRIGHT: (C)2012,JPO&INPIT【課題】旋回時にも圃場が均され過ぎないように整地できる対地作業用の旋回ロータを備えた苗移植機を提供すること。【解決手段】走行車体2の後部に圃場に苗を植え付ける苗植付部4の下部に圃場面を均す左右の整地ロータ27a,27bと、エンジン20の駆動力を後輪11に供給する左右の後輪ギアケース18を設けた苗移植機において、左右の前記ギアケース18から左右両側の整地ロータ27a,27aに駆動力をそれぞれ独立して供給する左右別々のロータ駆動軸70a,70bを設け、旋回動作させたときに、旋回内側の整地ロータ駆動軸70a,70bが旋回外側の整地ロータ駆動軸70a,70bよりも低速で回転する構成としたので旋回内側の整地ロータ27a,27bで圃場の泥土が柔らかくなり過ぎて流れてしまうことが防止できる。【選択図】図7
